Legendary strongman runs through Chelsea, strangely (8)
I believe the answer is:
heracles
'legendary strongman' is the definition.
The definition suggests a singular noun which matches the answer.
'runs through chelsea strangely' is the wordplay.
'runs' becomes 'r' (abbreviation in cricket).
'through' means one lot of letters goes inside another (inserted letters go through the word).
'strangely' indicates anagramming the letters.
'chelsea' anagrammed gives 'heacles'.
'r' inserted within 'heacles' is 'HERACLES'.
Can you help me to learn more?
(Other definitions for heracles that I've seen before include "Leachers (anag) - Greek hero (who laboured)" , "Mythical labourer" , "hero of superhuman strength" .)
